If you're anything like me, you greeted the news of Baldur's Gate 3's expanded evil endings in the mammoth Patch 7 with a "Oh, that sounds interesting, but there's no way I could stomach actually unlocking them." Luckily for us soft-hearted roleplayers, those bad boys are on YouTube in force, and they're well-worth seeing—even if it's just to give some added weight to your "canon" happy ending. Spoilers ahead for Patch 7's new endings.
There's the basic binary choice at the end of the game where you either destroy or enslave mind flayer superbrain The Absolute, with the new ending variations all flowing from the latter choice. There are a ton of different ways it can play out, with your character achieving the ending as a mind flayer or not, and with or without the support of the Emperor. If the Emperor's still around, you have the choice to either play second fiddle to him or betray him at the last second, usurping control as in the other evil endings.
